The first end of link block 21, the link block 21 is equipped with accommodating chamber 22, and the accommodating chamber 22 is in the link block 21
The end face of first end is equipped with the first opening 23, and the accommodating chamber 22 is in offering second on the outer circumference surface of the link block 21
When opening 24, wire drawing end pull rod 11 and link block 21 are fixed, the first end of wire drawing end pull rod 11 is prolonged by the first opening 23
It protrudes into the accommodating chamber 22；The second end of link block 21 is equipped with ball cup 28, and spherical card slot, gearbox are equipped in ball cup 28
Rocker arm 41 is realized by ball rod and ball cup 28 and is connected.
Clamping block 31, the clamping block 31 are detachably secured on the outer circumference surface of the link block 21, the clamping
The inner wall of block 31 is equipped with the second fastener 32 cooperated with first fastener 12, first fastener 12 and the second engaging
Part 32 cooperates so that wire drawing end pull rod 11 to be fixed in the accommodating chamber 22.
The working principle of above-described embodiment are as follows: wire drawing end pull rod 11 is extended into accommodating chamber 22 by the first opening 23,
The first fastener 12 for extending into accommodating chamber 22 is located exactly at the lower section of the second opening 24, and wire drawing end pull rod 11 reaches predetermined dress
When with position, the second fastener 32 of shackle member is extended into the second opening 24, is fixed with the realization of the first fastener 12, from
And solves the technical issues of bad control of screwing force caused by bolt connecting mode in the prior art, while it is difficult to reduce assembly
Degree, reduces assembly time.
Those skilled in the art are it is readily conceivable that the snap fit of the first fastener 12 and the second fastener 32 has
Many kinds, such as the modes such as fixture block and card slot, the present embodiment in order to which wire drawing end pull rod 11 is firmly secured on link block 21,
Prevent it from occurring device for elimination of axial-and radial-play in use, first fastener 12 and second fastener 32 are preferably
Mutually matched straight thread, the straight thread intermeshing of the two are fixed.
Clamping block 31 is fixed on link block 21 with dismountable fixed form, it is required that it is easy to loading and unloading and fixed,
Referring to Fig. 3 and Fig. 4, the two sides of second opening 24 are convexly equipped with wedge-shaped limited block group, and the clamping block 31 is concavely provided with the
One clamping groove 33, the second clamping groove 34 and third clamping groove 35, first clamping groove 33 and the third clamping groove 35 are symmetrical
It is set to the two sides of second clamping groove 34, the straight thread is formed in the bottom of second clamping groove 34, and described first
The spacing block set 36 of projection and the wedge-shaped limited block group cooperation on the inner wall of clamping groove 33 and the third clamping groove 35.Assembly
When, what first clamping groove 33 and the third clamping groove 35 were caught in the link block 21 is located at the second 24 two sides side walls of opening
On, second clamping groove 34 gos deep into the second opening 24, after spacing block set 36 slips over the lozenges of wedge-shaped limited block group, is formed solid
Fixing limit, the straight thread on the straight thread and clamping block 31 of wire drawing end pull rod 11 is intermeshed just at this time, by wire drawing end
Pull rod 11 is fixedly connected with link block 21.
Clamping block 31 is lost in order to prevent and convenient for assembly, the wedge shape limited block group includes along the link block 21
Excircle face ring the first wedge block 26 and the second wedge block 27 that set, first wedge block 26, second wedge block 27
Close to second opening 24, when spacing block set 36 is caught in the first 26 back of wedge block, the clamping block 31 is fixed on described
It on link block 21, but is not at this time gripping orientation, the retractable in accommodating chamber 22 of wire drawing end pull rod 11 adjusts position,
The purpose for the arrangement is that, in order to continue to assemble, being drawn in wire drawing end in order to which clamping block 31 to be pre-assembled on link block 21
After bar 11 extends into the predetermined position of accommodating chamber 22, as long as pushing clamping block 31, clamping block 31 is continued to slide over into the second wedge block
27 lozenges, and form fixed limit, at this time the straight thread on the straight thread of wire drawing end pull rod 11 and clamping block 31 this
When be intermeshed just, wire drawing end pull rod 11 is fixedly connected with link block 21.By straight thread mating reaction, guarantee cable wire
End pull rod can not move forward and backward in accommodating chamber 22.So that wire drawing end pull rod 11,21 relative position of link block are constant,
Wire drawing is not moved.From the purpose of not up to fixed length of string.
In order to enable the locking process of spacing block set 36 is more smooth, the spacing block set 36 is wedge structure, the limit
The lozenges of position convex block 36 and the lozenges of the wedge-shaped limited block group cooperatively form a pair of of sliding guiding surface, under clamping block 31
During pressure, the lozenges of the lozenges of the spacing block set 36 and the wedge-shaped limited block group cooperates, and descends pressure drag in this way
Power reduces, and clamping process is smooth.
As the optimal technical scheme of the present embodiment, the end of the first end of wire drawing end pull rod 11 is formed with limit
Platform 13, the limiting stand 13 are circular cone trapezium structure, and both ends trimming, central part is equipped with fluting 14, due to limiting stand 13
Pyramidal structure so that wire drawing end pull rod 11 is easily accessible 21 inner cavity of link block, and is difficult to.
Referring to Fig. 6, wire drawing end pull rod 11 shakes in accommodating chamber 22 in order to prevent.Ring on the inner wall of the accommodating chamber 22
Equipped with the annular boss 25 for limiting 11 play of wire drawing end pull rod.
Referring to Fig. 4, in order to enable clamping block 31 adapts to the wire drawing end pull rod 11 of a variety of outer diameters, second clamping groove
34 bottom is equipped with fixed block 37, and the first side of the fixed block 37 and the bottom profile of second clamping groove 34 match,
Second side of the fixed block 37 and the outer diameter of the first end of wire drawing end pull rod 11 match, second fastener 32
It is formed in second side of the fixed block 37.Fixed block 37 is set as dismountable structure in this way, facilitates exchange, to adapt to difference
Application.
As the optimal technical scheme of the present embodiment, the clamping block 31 is equipped with lightening hole 38, to reduce car body weight,
Lightening hole 38 also can be used as wire harness passing-hole simultaneously.
The course of work of the invention are as follows:
When the first wedge block 26 of spacing block set 36 and link block 21 on clamping block 31 cooperates, do not block for clamping block 31
Tight state.At this point, the first wedge block 26 limitation clamping block 31 is deviate from, the straight thread of wire drawing end pull rod 11 is straight with clamping block 31
Screw thread is unmated.Wire drawing end pull rod 11 can move in accommodating chamber 22.
When assembly, length of string is adjusted to after the size of needs, clamping block 31 is pressed, so that the limit convex on clamping block 31
Cooperate at second wedge block 27 of block 36 and link block 21.Clamping block 31 is gripping orientation at this time.Second wedge block 27 limitation card
The abjection of block 31 is connect, 11 straight thread of wire drawing end pull rod and 31 straight thread of clamping block cooperate.By straight thread mating reaction, guarantee to draw
Silk end pull rod 11 can not move forward and backward in accommodating chamber 22.So that wire drawing end pull rod 11,21 relative position of link block
Constant, wire drawing is not moved.To achieve the purpose that fixed length of string.
Structure, feature and effect of the invention, the above institute are described in detail based on the embodiments shown in the drawings
Only presently preferred embodiments of the present invention is stated, but the present invention does not limit the scope of implementation as shown in the drawings, it is all according to structure of the invention
Think made change or equivalent example modified to equivalent change, when not going beyond the spirit of the description and the drawings,
It should all be within the scope of the present invention.
